the বই have really confused me and I know that these guys in The Vampire Diaries are just actors and stuff, but since when has Elena been blonde lol?

Well,the বই are really different from the show, In the বই Elena is a Blonde and Bonnie's a red head,plus in the প্রদর্শনী There are some charecters that have never been mentioned in the বই and the opposite :)

she's been blonde since forever! the প্রদর্শনী is based on the very জনপ্রিয় book series. they've changed a bunch of things in the show, but it just makes it that much better and it's still awesome!
